Firms collaborate on controls upgrade
Balluff Inc. and Delta Computer Systems have developed a retrofit controls package for hydraulic-clamp injection presses that gives positioning feedback control for up to eight axes.
The closed-loop control packaging combines Delta's new RMC100 remote motion controllers with Micropulse linear position sensors from Balluff, of Florence, Ky.

Wayne offering lab test equipment
Wayne Machine & Die Co. of Totowa, N.J., introduced a lab-sized machine for making test specimens, and a flat die for sheet, cast film, extrusion coating and laminating in the lab.
Yellow Jacket Flat Dies feature a flexible lip so an operator can adjust the die's width where the sheet may be uneven. One bolt adjustment is placed along every inch of die width. The bolts face the die's rear for easy adjustment.
Wayne offers dies in widths from 4-8 inches.
On the test-specimen machine, an extruder fills the mold until a small amount of material exits a weep hole at the far end of the mold. That signals that the mold is filled. After cooling with water, the specimen is removed.
Wayne Machine said the specimen-maker can work with an existing single or twin-screw extruder with screw diameters of a quarter inch to 1 inch. Wayne also will supply a complete line with a new extruder.

Sandretto aims press at specialty molding
Sandretto USA Inc.'s new injection press, BN Multi-Melt Synchro, is aimed at specialty molding such as coinjection, multicolor, multicomponent and multimaterial.
The presses come in clamping forces from 120-550 tons.
Multi-Melt machines use dual injection units and Sandretto's five-point toggle clamp design.
Middleburg Heights, Ohio-based Sandretto is scheduled to deliver its first North American Multi-Melt press in March, to an undisclosed molder.

Jomar reduces cycle time on Model 135
Jomar Corp., an injection blow molding machine maker in Pleasantville, N.J., announced several improvements to its Model 135 midrange press.
Jomar has improved safety by completely enclosing the molding area, to conform with European safety standards. The machine can be used in clean rooms.
Jomar added a Bosch proportional hydraulic system, which reduces cycle times by three-quarters of a second. It removed cylinder-rod cushions to reduce maintenance. A clamp-pressure-reducing circuit allows the press to run smaller molds.
Also, the press has an Allen-Bradley SLC 503 controller with a color display screen.
